Thanks for your answer. I downloaded a binary RPM of squid 3.1
how can i confirm that has ESI support??
squid -v should contain "--enable-esi" as one of the features.
Requests received via a reverse-proxy port will have a
Surrogate-Capabilities header indicating ESI/1.0 protocol support when
they reach the origin server.

Hi
I'm planning to install a reverse proxy server with squid but one
of
the requisites is that it
should have ESI support.
Questions
Does squid have ESI support? is it good?
Yes, in Squid-3. It works pretty well in 3.1+, 3.0 works in a
dedicated
binary but does not interact nicely with several other proxy
features.
The initial sponsors saw the core parts of the protocol to
completion, so
that all works great with only an occasional bug. But some of the
more
complex pieces are not supported and/or noticeably buggy. The squid
bugzilla
has the list of known issues.
How do i configure ESI support in squid??
Depends on your version. Ensure that --enable-esi is built in with
XML
libraries.
Once that is done Squid will auto-magically start advertising the
relevant
Surrogate-Capabilities to the origins. The server response type
determines
whether it is processed or not.
Are there any links to examples or tutorials of ESI configuration
in
squid??
Very few unfortunately certainly nothing comprehensive. W3C specs
have some
good examples. http://www.w3.org/TR/esi-lang. But like HTML, the
devil is in
the details of how you structure the XML tags in the ESI page object
and
what caching controls you place on the raw original objects.
Wikipedia has a list of common tools like Drupal and Zope which you
can use
to play with it
